DENVER (AP) — One of the FBI's Ten Most Wanted Fugitives has voluntarily returned from El Salvador to Colorado to face a first-degree murder charge in a 2011 slaying, the FBI said Wednesday.

Edwin Ernesto Rivera Gracias landed in Centennial, Colo., with FBI agents Wednesday afternoon, less than two weeks after being added to the Ten Most Wanted Fugitives list.

The surrender of Rivera Gracias, a citizen of El Salvador, came after the FBI announced a $100,000 reward for information leading to his arrest. The FBI isn't releasing further details related to the reward.

Rivera Gracias was wanted in Jefferson County in the slaying of Richard Limon, 69, whose body was found near a guardrail on Lookout Mountain in 2011. He had been stabbed multiple times.

An affidavit filed in federal court alleges Rivera Gracias had talked about killing Limon because of allegations that Limon molested Rivera Gracias' girlfriend. The girlfriend was the daughter of Limon's wife.

Limon's wife and another man pleaded guilty to second-degree murder in the case and have been sentenced to prison. Rivera Gracias' girlfriend pleaded guilty to being an accessory to commit murder.

"This outcome provides assurance for victims and prosecutors throughout the United States that those who commit egregious crimes will be pursued around the globe," said Steve Olson, FBI Denver acting special agent in charge, in a written statement.
